We hear a lot in the media about the solar car, and that it would be the future car. We see also several examples of this kind in various parts of the world. In this work we would try to do a study which will respond to this question: whether is…

In this paper, a low cost and an easy to implement solar tracker system is presented. The design of the system is based on the fuzzy reasoning applied to crisp sets. In this case, it can be easily implemented on general purpose microprocessor…

Ce travail présente une modeste contribution sur le domaine des éléments finis. On a essayé de résoudre l’équation de Poisson avec les conditions aux limites de type Dirichlet dans un domaine quelconque bidimensionnel simplement connexe. Après une…

Two-dimensional, compressible Euler and Navier-Stokes equations are solved numerically by finite volume method to predict steady and unsteady flows around bluff-bodies. An unstructured grid generator code is linked in an automatic way to the flow…

Direct torque control (DTC) of induction motor (IM) is important in many applications. In this paper presents a three-level direct torque control with 24 sectors is applied for IM using PI-flou controller and hysteresis regulators based in artificial…

In this paper we study the stability of input voltages of the cascade consisting of a photovoltaic inverter and a three-level structure NPC, feeding a synchronous machine with permanent magnets (PMSM) commissioned by the speed command flow oriented.…

Wind data analysis and accurate wind energy potential assessment are critical factors for suitable development of wind power application at a given location. This paper explores wind speed distribution to select the two-parameter Weibull methods that…

This paper deals with the development of neural network IC-based variable step size MPPT controller. The proposed neural network MPPT controller is firstly, developed in offline mode required for testing different set of neural network parameters and…

Les espaces publics ouverts, surtout les places publiques sont pour la rencontre de la population, la communication, la convivialité, etc… Afin que ces espaces jouent leur rôle, il y règne un environnement physique confortable. L’usage optimal de ces…

Cet article présente la conception de la stratégie de gestion et de contrôle pour les systèmes photovoltaïques autonomes – Station de recharge solaire pour véhicules électriques. La stratégie proposée est basée sur le contrôleur combiné de suivi du…
